Laminated shingle with wider nailing zone

ABSTRACT

A multiple-layer laminated shingle and a method of making the shingle are provided, in which at least one adhesive of high temperature resistance is applied for securing the shingle layers together, to reduce reliance on a roofer having to fasten (via nails, staples or the like) through a narrow headlap zone of a posterior shingle layer in order to secure the posterior shingle layer to a roof, such that a vertically wide portion of the headlap area of the anterior shingle layer is presented to the roofer as a nailing zone.

BACKGROUND OF THE INVENTION

[0001] Laminated shingles are known in the art to be made from asphalticroofing material overlaid upon one another, and secured together bymeans of an adhesive to provide a shingle having a thicker section. Theanterior layer of the shingle has alternating tabs and cut out portionsin the form of slots of various dimension in the lower end of theshingle, and an upper end of the shingle that is not divided into tabs.The posterior shingle layer, often called a backing sheet is applied,generally to the rear surface of the lower end of the anterior shinglelayer, covering the rear surfaces of the tabs, such that the two shinglelayers are not coextensive in area.

[0002] In applying the shingles to a roof, by means of fasteners such asnails, staples or the like in accordance with the teachings of the priorart, there is a longitudinal strip of double thickness through which thenails, staples or the like fasteners must be applied, in which they willpass through both shingle layers, such strip being above the area of theslots, but below the upper edge of the posterior shingle layer.

[0003] In order to most efficiently package a plurality of shingles in agiven bundle, the posterior shingle layer is generally less than onehalf the width of the shingle, such that the shingles may be alternatedin packaging without a stack of packaged shingles forming a “hump”.Typically, a backer strip or posterior shingle layer for a shingle of 12inches in width, is usually 5⅞ to 5{fraction (15/16)} inches wide inorder to avoid the creation of an unduly high zone or “hump” in themiddle of the shingle bundle, which is not desirable. Such 12 inch wideshingles then typically have an exposure width of 5 inches, leaving thecommon bond area between the laminated shingle layers to be alongitudinal strip of less than 1 inch in width.

[0004] Professional roofers find this width too narrow, as it interfereswith efficient fastening of shingles to a roof, slowing down the speedof shingle application.

[0005] One approach to the problem is set forth in U.S. Pat. No.6,145,265, granted Nov. 14, 2000, the complete disclosure of which isherein incorporated by reference. That approach has been to enlarge thewidth of the posterior shingle layer, to provide a larger (higher)common bond strip, of greater width than 1 inch, so that the nails,staples or like fasteners have a wider strip for passing through twolayers.

[0006] Where laminated shingles have a common bond area that is toonarrow, such as 1 inch or less, there can be a tendency for roofers tofail to apply the nail or staple fasteners into the common bond area,but to apply their fasteners above the common bond area, such that thefasteners pass through only the anterior shingle layer, and do notintercept the upper portion of the posterior shingle layer.

[0007] On roofs having a gentle slope or pitch, such misapplication ofshingle fasteners may not be so susceptible to later problems. However,in roofs of steep pitch or slope, especially in warmer weather, such assummer weather, and in more southerly locations where roofs aresubjected to more sun and greater heat in the summer, the temperature ofa roof, particularly a dark roof, can reach 170° F. In more northerlylocations in the summer, the temperature of a lighter colored roof, suchas a white or light gray roof, in summer conditions may not reach atemperature higher than 140° F.

[0008] Most particularly, in more southern geographic areas, during thesummer, and wherein roofs are of darker color, the temperature of theroof may approach the softening temperature of the normallybitumen-based adhesive, such as asphalt, which adheres two laminatedlayers of the laminated shingle together. With such softening of thebitumen-based adhesive, there leaves the possibility, especially forroofs of steeper pitch or slope, that the posterior shingle layer of anygiven shingle, if the fasteners have not penetrated such posterior layerwhen the shingle was applied to the roof, the posterior shingle layer,under its own weight, may overcome the adhesive quality and deformationresistance of the softening bitumen, and slide out beneath the anteriorshingle layer, at least compromising the quality of the roof.

SUMMARY OF INVENTION

[0009] The present invention is directed toward solving the aboveproblems by providing a laminated shingle in which a stronger adhesiveis applied, having a higher heat resistant temperature than the adhesivethat normally fastens the shingle layers together, such that under hotconditions and on steep roofs, the stronger adhesive will be sufficientto keep the two shingle layers adhered together even if the heatresistant temperature, or softening point temperature of a prior artshingle laminating adhesive is reached, such that if fasteners that areused to fasten the shingle to a roof are applied through the anteriorshingle layer only and not the posterior shingle layer, the posteriorshingle layer will nevertheless remain in place, adhered behind theanterior shingle layer.

[0010] A wide fastening zone is provided on the shingle, not limited toinserting fasteners through the double layers of shingle, but whereinthe fastening zone is sufficiently wide to embrace at least a portion ofthe anterior shingle layer only, having no posterior shingle layertherebehind. In another facet of the invention, optional single shinglelayer and double shingle layer areas are presented corresponding towider and narrower fastening zones, respectively, leaving the installerthe option of nailing through two layers of shingle, or only a singlelayer of shingle, when nailing or otherwise fastening a shingle to aroof. The fastening zones may be defined by demarcation limits, such asmarked lines, lines of adhesive, or combinations of both.

[0011] Accordingly, it is a primary object of this invention to providea novel multi-layer laminated shingle, in which at least one highsoftening point adhesive is used to secure the shingle layers together.

[0012] It is another object of this invention to accomplish the aboveobject, in which if more than one adhesive is used, one of the adhesiveshas a heat resistance to a temperature level that is higher than that ofthe other adhesive.

[0013] It is a further object of this invention to accomplish the aboveobjects, wherein temperature levels normally reached during variousseasonal parts of the year, and even for darker shingles, are notsufficiently high to soften an adhesive that is used to adhere theshingle layers together.

[0014] It is yet another object of this invention to provide a laminatedshingle having a wide nailing zone, without having a wide double-layernailing zone, by using a high temperature softening point adhesive or anadhesive that does not soften at high temperatures or an adhesive havinga high shear modulus, to secure the layers of the laminated shingletogether, such that it is no longer necessary to nail the shinglethrough both layers of the laminate in order to retain the posteriorlayer on a roof.

[0015] Other objects of the invention comprise providing optionalfastening zones for fastening a shingle to a roof through either onetwo-layer fastening zone, or through a single-layer fastening zone, orcombinations of both.

[0016] Other objects and advantages of the present invention will bereadily apparent upon a reading of the following brief descriptions ofthe drawing figures, the detailed descriptions of the preferredembodiments, and the appended claims.

DETAILED DESCRIPTIONS OF THE PREFERRED EMBODIMENTS

[0025] Referring now to the drawings in detail, reference is first madeto FIG. 1, wherein a prior art shingle is generally designated by thenumeral 10, as having an anterior shingle layer 11 and a posteriorshingle layer 12. The anterior shingle layer 11 has a plurality of tabs13, separated by substantial cut-outs 14, spaced apart by the tabs 13,and formed as sizable slotted openings between the tabs 13. The shingleof FIG. 1 is often referred to as a multiple-ply dragon-tooth design.

[0026] The anterior shingle layer 11 has a front surface 15 and a rearsurface 16. The posterior shingle layer 12 has a front surface 17 and arear surface 18. The posterior shingle layer 12 has an upper edge 20.The cut-outs 14 in the anterior shingle layer 11 have an upper edge 21.Widthwise, the longitudinal area between the upper edge 21 of t h ecut-outs 14 and the upper edge 20 of the posterior shingle layer definesthe common bond area 22, which runs from the right-most edge 23 of theshingle of FIG. 1, to the left-most edge 24. This common bond area, inwhich the two shingle layers 11 and 12 are co-extensive, defines thenailing or stapling zone that is desired by many installers for applyingshingles to a roof.

[0027] Referring to FIG. 2, a description of the manufacture of shinglesin accordance with this invention will be understood. In FIG. 2,continuous layers of shingle material for making the posterior shinglelayers in accordance with this invention and the anterior shingle layersin accordance with this invention are shown at 30 and 31, respectively,being conveyed along rollers 32 and 33, respectively in theirlongitudinal paths of travel, as indicated by the arrows 34 and 35respectively. For the layer of posterior shingle material 30, a cuttingroller 36 and associated back-up roller 37 are shown, and for theanterior shingle layer 31, cutting and back-up rollers respectivelynumbered 40 and 41 are shown, with the roller 40 having a plurality ofcutting blades 42, for cutting the cut-outs similar to those 14 shown inFIG. 1. The layer 31 of shingle material then passes over a pair ofadhesive applicators 43 and 44, and the layers 30 and 31 of shinglematerial are brought together after passing around suitable turningrollers 45, 46, 47, 48 and 50, to be laminated together by adhesivesdelivered from the applicators 43 and 44, to then pass between cuttingand back-up rollers 51, 52, whereby cutting type blade means 53 seversthe laminated shingle material into discrete laminated shingles 54 atthe left end of FIG. 2.

[0028] It will be understood that various techniques for makinglaminated shingles may be employed, such as those set forth in U.S. Pat.No. 6,092,345, issued Jul. 25, 2000.

[0029] Referring now to FIG. 3, it will be seen that, in one embodimentof the invention, horizontal adhesive strips S1, S2 and S3 of asphalt,bitumen or other adhesives are applied from rollers R1, R2, R3,respectively, of adhesive applicator 44, as the sheet of shinglematerial 31 moves leftward in the direction arrow 35 in FIGS. 2 and 3.It will also be seen that the adhesive applicator 43 is shown asapplying a plurality of spots 55 of adhesive onto a rear surface of ananterior layer of the shingle material 31, in zones of tabs T betweenspaced-apart cut-outs 56, below the upper edge 57 of the cut-outs at avertical location where strips of adhesive S1, S2, S3 are not applied.The adhesive applicator 43, like the applicator 44, may be of any typefor applying an adhesive, from a single brush, roller, or the like, ormay be of a type for applying adhesive from a two components adhesiveapplication gun, as shown. In the applicator 43, two discrete adhesiveapplicator lines 58, 60 are shown, for delivering adhesive to two sides61, 62 of an adhesive applicator gun, wherein the two component adhesivewill undergo a chemical reaction when the two components which arenormally separated combine within the gun, with the chemical reactionthereby occurring forming a chemical bond that secures the shinglelayers 30, 31 together. Alternatively, one or both adhesive lines 58, 60may deliver a conventional hot melt adhesive, such as ethylene vinylacetate, a polyamide, a glue, or a bitumen-based adhesive, such as anasphalt, or the like. The adhesive applicator 44 will generally apply anadhesive of bitumen, asphalt or of any other type suitable to secure thetwo layers of shingle material 30, 31, together.

[0030] With reference to FIG. 4, it will be seen that a shingle 70 inaccordance with this invention is shown as having anterior and posteriorlayers 71, 72, with a common bond or headlap area 73 shown therebetween,between the upper edge 74 of the posterior shingle layer 72 and theupper edge 57 of the cut-outs 56 in the anterior shingle layer 71. Alsoshown in phantom are the adhesive dots or spots 75, (like those 55 ofFIG. 3), which secure the two shingle layers together, and which have aheat resistance at a temperature level that is higher than the heatresistance of the adhesive of the strips S1, S2, S3 applied to tabs 59and headlap zone 73, such as via applicator 44. It will be apparent thatthe application of adhesive, instead of being drops or spots 75, may bea continuous strip, between the right-most end 76 of the shingle 70 ofFIG. 4 and the left-most end 77, as may be desired. Possibly also, theadhesive applied via applicator 44 will be co-extensive with thoseportions of the rear surface of the anterior shingle layer 71 that formthe tabs 59, or in horizontal strips as shown or as spots (not shown).The adhesive that is applied as spots 75 will preferably be that whichhas the higher level of heat resistance, to at least 140° F., and morepreferably to at least 170° F. along the common bond area 73, betweenthe right-most end 76 of the shingle 70 of FIG. 4 and the left-most end77, as may be desired. Preferably, the adhesive applied via applicator44 will be co-extensive with those portions of the rear surface of theanterior shingle layer 71 that form the tabs 59. The adhesive that isapplied to the common bond area 73 will preferably be that which has thehigher level of heat resistance, to at least 140° F., and morepreferably to at least 170° F. Such adhesive will have a softening pointthat is at least as high as 197° F., and more preferably, at least ashigh as 240° F., and perhaps as high as 275-300° F. Alternatively, theadhesives that form strips S1, S2, S3 and spots 75 may be applied to theanterior surface of the posterior shingle layer to secure the layers 71and 72 together, or to contacting surfaces of both layers 71, 72.

[0031] The adhesive that is applied as spots 75, or in some other form,and which is a high temperature softening point adhesive, and preferablya high heat resistance adhesive may comprise a non-bituminous adhesivehaving heat resistance to a predetermined temperature level, which maybe an epoxy adhesive and/or may be a two-part thermal set adhesive or aone-part thermal or moisture set adhesive and will also preferably havea high shear modulus for securely holding the two to layers of shingletogether. Such sheer modulus (SM) is defined as the ratio of shearstress to shear strain. Thus, if shear stress is defined as shearingForce divided by the Area and if shear strain is defined as the changein dimension (x) relative to the original dimension (y), then shearmodulus is defined as: ${SM} = \frac{F/A}{x/y}$

[0032] In the metric system, the modulus is expressed in Newtons persquare meter (Newtons/m²).

[0033] A preferred shear modulus in accordance with the presentinvention is one that is greater than 10,000 Newtons/m² and having ashear modulus after 1000 seconds of stress exposure at constant loadingat approximately at least 150° F., greater than 1000 Newtons/m².

[0034] Referring now to FIG. 5, it will be seen that a shingle 90 isprovided, comprised of two shingle layers 91 and 92, that are adheredtogether in a manner similar to the shingle layers of FIG. 4, such thatthe same will not be repeated here.

[0035] However, in FIG. 5, it will be seen that a pair of rows ofsealant 94, 95 are shown on the anterior surface of the anterior shinglelayer. These rows of sealant may preferably be provided with strips ofrelease paper thereon, when the shingles 90 are packaged together, to beremoved prior to installation on a roof, or in the alternative, thoseportions of a shingle that are packaged adjacent the shingle 90 when thesame are packaged together, may have release paper on those portions ofthat shingle that would be packaged against the sealant rows 94, 95, inthe packaged condition, to prevent adjacent shingles in a given packagefrom sticking together. In any event, a shingle as shown in FIG. 5,prior to its installation on a roof, will not have release paperdisposed over sealant 94, 95, at that time that the shingle is appliedto a roof.

[0036] It will be seen that the sealant row 94 is provided generally inthat headlap portion 96, below the upper edge 93 of the posteriorshingle layer, and above the upper edge 97 of the cut-out in theanterior shingle layer, to define for the shingle installer, on the topsurface of the shingle as it is being installed on a roof, a lower endto a nailing zone, the upper end of which nailing zone 98 is defined bythe row of sealant 95, placed as shown.

[0037] In the embodiment of FIG. 5, the rows of sealant 94, 95, arespaced apart a distance “c”, which may be, for example, on the order oftwo inches, whereas the distance above the upper edge 93 of theposterior shingle layer, that the row of sealant strips 95 is disposedmay be a distance “b” that is on the order of 1⅞ to 2 inches, and withthe headlap distance “a” being an overlap on the order of ⅜ inches or ½inches, or even 1 inch. The wide nailing zone 98 that is displayed to aroofing installer, thereby suggests to the roofer, staples or the like,which secure the shingles to a roof, should be essentially through thesingle layer 91 of shingle material of the shingle 90, essentially abovethe upper edge 93 of the posterior shingle layer, because of the closeproximity of the sealant layer 94 thereto, and below the line defined bythe strips of sealant 95.

[0038] It should be apparent from the above that, in accordance withthis invention, the overlapping headlap zone “a” can be reduced,resulting in a saving in material, and packaging of shingles withoutcreating a “humping” when shingles are packaged due to excessive heightof the posterior shingle layer, while allowing for rapid installation ofthe shingles in the field.

[0039] However, instead of the row of sealant 95 of FIG. 5, there isprovided a scribe or score line 105, which, in lieu a row of sealant atthat location, can provide for the roofing installer, an upperindication of the nailing zone 98.

[0040] It will be apparent from the foregoing that if fasteners happento be applied through only the anterior shingle layer 71, and throughonly that portion of the anterior shingle layer 80 that is above theupper edge 74 of the posterior shingle layer 72, then with the strongeradhesive 75 applied in the common bond area e.g. like that shown in FIG.4, the posterior shingle layer will remain in place even under hightemperature conditions and on roofs of steeper slope or pitch.

[0041] With reference now to FIG. 6, it will be shown that there is ashigle that, for the most part, is constructed like the shingle of FIG.5, with the shingle 100 being comprised of anterior and posterior layers101, 102 the posterior layer of which has an upper edge 103, and with arow of sealant 104 being disposed on the anterior shingle layer 101similar to the row of sealant 94 of FIG. 5.

[0042] Referring now to FIG. 7, an alternative multi-layer laminatedshingle 120 is shown, having anterior and posterior layers, 121, 122,respectively, with cut-outs 123 in the anterior shingle layer, spacingapart tabs 124 of the anterior shingle layer, and having a width for theanterior shingle layer “m” of 12 inches, with the posterior shinglelayer having a width “q” of approximately 6 inches, leaving a commonbond headlap area above the upper edge 125 of the cut-out areas 123,designated as “n”, of approximately ⅞ inch to 1 inch.

[0043] Demarcation limits or lines 126, 127 and 128 are shown, which aremarkings to guide a shingle installer, as to where the nails, staples orother forms of fastener should be placed, to fasten the shingle 120 to aroof or the like. The line 126, 127 and 128 may be discrete lines, asshown, or may be demarcation limits in the form of upper and lower endsof bands, of different color, shading, etc, as desired. The demarcationlimits 126, 127 and 128 may also be scribed lines, or any other form ofmarking to enable a shingle installer to see the zones that suchdemarcation limits present for fastening the shingle to a roof.

[0044] For example, the width of the zone between lines 126 and 127, of“o” may perhaps be {fraction (5/16)} inches, for guiding the installeras to where a fastener may be applied to assure that it will go throughboth posterior and anterior shingle layers, if the perceived security ofnailing through two layers is desired.

[0045] The distance between demarcation limits 126 and 128, as shown by“p”, may, however, be on the order of 1¾ inches, more or less, to definea wider fastening zone, for instances where the installer is comfortablefastening the shingle through either a shingle thickness in the anteriorshingle layer only, or a double thickness portion through both theanterior and posterior shingle layers.

[0046] Alternatively, if the installer is comfortable nailing onlythrough a single layer of the laminated shingle; namely the anteriorshingle layer, the fastener can be applied between demarcation limits127 and 128, in a zone of approximately 1⅜ inch in width. The layers 121and 122 of shingle 120 are adhered together by any of the highertemperature or high shear modulus adhesives discussed above, that willsecurely hold them together under the above-mentioned conditions oftemperature, slope, etc.

[0047] With reference now to FIG. 8, it will be seen that a shingle 130,comprised of anterior and posterior shingle layers 131, 132 is alsoprovided, and is constructed essentially similarly to that of theshingle of FIG. 7, except that the demarcation limits or lines 136, 137and 138 of the shingle of FIG. 8 are illustrated as being broken orspaced-apart lines. Such lines may be scribe lines, colored lines,portions of a bands or the like, or may be comprised of lines ofadhesive. The dimensions m′, n′, o′, p′, and q′ may be similar to thedimensions m n o p q of FIG. 7, just as the adhesive that adheres layers131 and 132 together may be as described above for the shingle of FIG.7.

[0048] Accordingly, it will be apparent from the foregoing that theobjects of the present invention are satisfied, and that variousmodifications may be made in the details of construction, as well as inthe use and operation of shingles in accordance with the presentinvention, all within the spirit and scope of the invention as definedin the appended claims.
